JONATHAN BENNET, OF'AMENA, 'NEW YORK.

SHINGLE-MACHINE.

Specification of Letters Patent No. 4,678, dated July 31, 1846.

To all 'whom 'it may concern:

Be it known that I, JONATHAN BENNET, of Amenia, in the county ofDutchess and State of New York, have invented a new and useful Machinefor Cutting Shingles, which is described as follows, reference being hadto the annexed drawings of the same, making part of this specification.

Figure l is a perspective view of the machine. Fig. 2 is a verticalsection on the line, of Fig. l. Fig. 3 is a front elevation of the gatedetached fromthe frame. Fig. t is a horizontal section on the line m ofFig. l.

The nature of my invention and improvement consists in the arrangementand adaptation of two knives to asliding frame in such manner as to cutat each down motion of said gate, two shingles, each from butt to tip.Also in the adjustment of a spring rest to the table in such way as toprocure uniform pieces to be severed from the block at one stroke, whilethe block is at rest. Also the direct presentation of the block to theknives in the successive motions of the gate or frame instead of thevibrating manner of presenting the block as in other machines at eachstroke of the knife. And also in the manner of bringing the block to aproper size by first straightening it at one side with the knives andthen changing it so as to bring the straight side of the face of thegage block, by which process shingles of uniform width are produced anda saving of timber effected.

To enable persons skilled in the art of making shingles to make and usethis machine t-he following description of it is given- Description-Crepresents the frame, A the sliding gate to which the knives, plates,and cam are secured. b1 b2 are the knives for severing the shingles fromthe block. p1 p2, the gage plates; K the cam; M-the bench; H the gageblock to which the shingle bolt is dogged.

N N are parallel grooved guides for guiding the gage block.

O O are two dogs for dogging the bolt to the block.

L is a link for attaching the block H to the lever I for operating it.

J is a bed plate secured to the top of the table and upon which theblock with the bolt dogged thereto slides.

G is a spring rest for increasing the width of the table in order tosustain the outer edge of the shingle-bolt during the passage of thelower knife through the bolt in severing a shingle therefrom. When theupper knife b2 arrives at the bolt this spring rest is pushed back bythe cam K in order to allow the knife to` pass through the bolt withoutcoming in contact with the said spring rest. It is fastened by one ofits ends to the table by bolts, or other suitable fastenings. The outerend G1 is loose and plays back and forth, or toward, or from, the

knives in a groove made in the table, of such size and form as to allowof this movement of the spring rest. Said groove is marked g in thedrawings. The bed plate J (over which the shingle bolt slides) is placedpartly over this groove in such manner that the spring rest can movefreely under it without touching the said bed plate. When the springrest is extended its outer edge is parallel and in the same verticalplane with the face of the lower knife b1 and gage plate p2; and whenthe rest G is contracted or forced back into the groove g byy the cam Kit will be parallel and in the same vertical plane with the face of theupper knife and lower plate p1. The upper and lower knives and platesare arranged so as to cut the butts and tips of two shingles at everydownward motion of the gate-that is to say the end f of the knife b1 isset back from the face of the gate and on aline with the plane of thegage plate p1, and the end p11 of the gage plate p1 is set back from theend d of the knife b1 equal to the thickness of the butt of the shingle.The two ends Z e of the knife b2 are to be in the same vert-ical planewith the end al of the knife b1, and inner edge of the bed plate` J,(see Fig. 2)- but the end of the gage plate p2, next the end e of theknife b2 is to be set back from the face of the gate or knife b2- equalto the thickness of the butt of the shingle; the other end is to be inthe same plane with the knife at cl. The operation of the gate of themachine is the same as in other shingle machines in use that is to sayit is made to slide vertically up and down between fender posts by theapplication of any convenient power applied to the lower cross bar ofthe at one Complete downward motion of the l0 gate, but the arrangementand operation of gate, cutting both, from butt to tip without the knivesis different as above set forth. changing the block or shingle bolt.

What I claim as my invention and desire his 5 to secure by LettersPatent is- JONATHAN X BENNET The peculiar arrangement of the knives inmal-k combination with the gage plates and spring l/Vitnesses: rest insuch way that their combined action NATT. P. PERRY, shall ezeet theproduction of two shingles HENRY I. FULLER.
